LOS ANGELES,CALIFORNIA, ASSIGNORS TO I FIBBE'BOARD PRODUCTS INC., 013 SAN FRANCISCO,CALIFORNIA, A CORPORATION OF DELAWARE CARTON Application filed July 6,

The invention relates to cartons, and particularly to folding cartonsmade from fiberboard and the like.

One of the objects of the invention is the provision of a carton .inwhich the bottom is supported on flanges running along the lower ed esof the carton.

other object of the invention is the provision of a folding carton madeup from a single sheet of fiberboard or similar material,- and in whichthe supporting flanges, along the bottom edges are formed by the unionof adjacent portions of the side and bottom.

Another object of the invention is the provision of a folding carton ofsuch shape as to permit the circulation of air about the bottom and topwhen alone or when stacked with other similar cartons.

Our invention possesses other objects and valuable features, some ofwhich will be set forth in the following description of our inventionwhich is illustrated in the drawing forming part of the specification.It is to be understood that we donot limit ourselves to the showing madeby the said description and drawing, as we may adopt varying forms ofour invention within the scope of the claims.

Referring to the drawing: Figure 1 is a plan view of the blank fromwhich the carton is folded up.

Figure 2 is a perspective view of the formed carton, partiallycollapsed.

In terms of broad inclusion, the device of fiberboard or other suitablematerial, having integrally formed flanges extending downwardly'from thebottom thereof to provide supports, so that the bottom is raised above49 the plane on which the carton rests. The

bottom of the carton therefore provides a resilient seat or support foreggs and other articles of fragile nature; and the circulation ofairunder the bottom is facilitated. The sides and ends of the cartonaresuitably creased to provide inwardly extending folds, so that after.formation the carton may be collapsed into a flat package for storageand shipment. When the carton is set up and filled with eggs, which arepreferably sepa- 1929. Serial No. 376,370.

rated by I partitions of fiberboard in the 2 prises a single sheet offiberboard, cut by suitable dies in the form indicated in Figure 1 ofthe drawing, and creased and folded as indicated by the dotted lines ofthe figure.

The blank shown comprises the area 3 forming the bottom of the box, theareas 4 and 6 comprising the front and rear sides, the areas 7 and 8comprising the ends, and the area 9 comprising the top.

The sides are provided with tabs 11, pref-- erably secured by adhesiveto'the end areas as shown in Figure 2; and the top is provided with aflap 12, adapted to be tucked into the package after the contentsare'placed therein. Each of the end areas 7 and 8 are creased along thelines 13 so that they tend to fold inwardly, as shown in Figure 2; andsimilar creases 14 are provided adjacent the ends of the front side 4 ofthe carton, so that by the united action of these creases, the front maybe folded down against the bottom, the ends in upon the front, and therear and top down over all, making a fiat package for storage andshipment.

The bottom edges of the sides are indicated I by the lines. 16; thematerial being creased along these lines and folded back to f the line17, where it is again creased; the fold however being in the oppositedirection. The long narrow strip 18 between these two lines 16 and 17,on each side, constitutes a flange folded downwardly from the bottom;and these strips'are preferably adhesively united respectively to thoseportions of the adj acentsides of similar area and with which theycontact whenthe material is creased along the line 16. The adhesiveunion of the two strips forms a relatively heavy and stifl flange havingthe necessary strength for its function.

- Thus a heavy flange is formed at the lower edge of the side andunderlying the bottom.

Whenthe carton is fully opened, as sug 1D i straightens out into theplane of the bottom.

a In the two-by-six size illustrated, the flanges along the two longsides of the carton are quite suflicient to perform the functiondesired, but it is obvious without special illustration that similarflanges could be provided across the ends of the carton if made in athree-by-four size.

Our carton is customarily used with a filler of any desirable type; andwhen so.

equipped an individual pocket is provided for twelve eggs, thespringiness or resiliency of the bottom preventing injury under anyordinary handling. Since the bottomof the carton is raised from theplane of the support air maypass freely under it so that refrigeration othe stacked cartons is facilitated.

We claim:

1. A foldable collapsible carton formed of a single blank and havingbottom, end and side walls, the portions between said bottom and sidewalls only being provided with double crease lines, said bottom and sidewalls being reversely folded on said crease lines when the carton is setup to provide depending anges of double thickness of material formed bylongitudinal legs integral with the side and bottom walls and extendingonly along the sides of the carton, so as to elevate the bottom andprovide an unobstructed passageway under the bottom between saidflanges, the legs of said flanges being secured together to form rigidextensions of said sides, and said ends and one of said sides beingprovided with creases whereby both of the sides and ends fold inwardlyto fiat collapsed position and outwardly to set up position withoutbending the flanges which form rigid extensions of the sides, the sidesand their respective rigid extensions turning about a hinge line formedby the junction of said flanges with said bottom.

2. A. foldable collapsible carton formed of a single blank and havingbottom, end and side walls, the portions between said bottom and sidewalls only bein provided with double crease lines, said bottom and sidewalls being reversely folded on said crease lines when the carton is setu to provide depending flanges of double thic ness of material formed bylongitudinal legs integral with the side and bottom walls extending onlyalong the sides of the carton, so as to elevate the bottom and providean unobstructed passageway'under the bottom between said flanges, thelegs of said flanges being secured together to form rigid extensionsaevaaeo set our-hands,
